I don’t know why this took so long to click with me, but set your lens back to infinity once you’ve finished shooting. This will make lining up your next shot much faster. If your subject is close to infinity (as many are) then you are already focused. If it’s closer then you already know which direction to turn the lens – the only way it will move. Maybe others are better than me, but I find there is nothing worse than a subject approximately 3 meters away and a lens set to three meters. I always have to waste time wiggling it to figure out which way is correct.
